ln, the construction illustrated in Fig. 1 center sill heving 'two en@ sections 9, .92. and e inizidlesection 10.- Tiie centerl sill may be U-slzepeor invertetltleshepe cross section, or it may be rectengulsr in. cross sec- -ticntfnronglront leireth, .but -it is mede Lonisin the county of St. Louis City and 'l State ci Msssouri, neve invented new end jects upward through U--sliepe or inverted' U-shepe the adjacent ends ot the sections. ere preferably mede rectangular or box shape. vThus I lieve shown a center sill of inverted U-shepe in cross lsection (Fig. 8) and et the adjacent ends of the three sectionse. cross Weber ber 11 isprovided et the bottom of each section which makes the adjacent; ends of the sections rectsngulsr onbox sliti'pe (Fig. 2). The end sections of the center-'sill are connected to then/riddle section et 'the cross ties-12, the adjacent ends of the" n-center sill sections meeting et the middle oi-.the cross ties, as clearly shown in. Figs. l, 2. @sich cross tie (Fig. is rvirled with s. centre-l recess 13V to receive t e center sill end also with two or more integral studs i4 which project up through bosses li in the crosswebs or bars 1'1. The center sill sections are provided with outwardly projecting lugs 15 et the top which rest in depressions 15 in the to of the cross ties. A. cover plete 16 is seats on the adjacent ends of the center sill sections,-

in depressions 16 therein (Fig. 2) and 'on the lugs l5, in the depressions 15 (Fig. 5) so that seid plete will lie iiusli vwith the top ol the center sill and the cross tie. Rivets or bolts 17 pass through the cover plete, lugs 15 and top web 12 of the cross tie to festen seid parts togetherJ and rivets 01 bolts 17I also testen the cross tie te the sides of the center sill (Fig. 5). The body bolsters 18 :irc each provided with a recess 18, like the cross ties, to receive the center sill (Fig. 4) and the letter has a cross web 18 at its bottom Wliichmskes the center sill rectengu lar or box shape :it the holsters. A stud 1.9 is. meile .integral with the bolster and it proen opening 19 in the Web i8 oi the conter sill. The center sill is provided with lateral lugs ZOWliicli lit in depressions 2i in the tog of the bolsters and rivets or bolts 22 pass t rough these lugs 2U end thel top 18 of the holsters to festen the bolsters and the center sill together'. lnsteed of' providing two studs 11i end one stud 19 l may use as many studs ss may be found. desirable. The center sill sections ere provided with lateral lsnges 23 et the bottomT except Where the center sill engages the cross ties and the holsters. The end sills 24 may he made in any suitable manner, separate from the other parts of the underiraine, as shown, or cast integral with 'the end secn tions of thev center sill. The side sills 25 may be made otchannel iron oixfin any other suitable nianncr and secured to the ends of the cross ties, holsters and einlsills, The stringers 26 may be supiorted in any suitable manner on the unleifranie. The hol sters are provided with integral centery hearin s 27 and side hearings nstead of making the center sill in three sections connected at the cross ties, as heretofore described, l may make it in any other number ol sections and in Fig. 9 I have shown a construction in which there is but one cross tie 29 and the center sill E() is made in four sections connected at the cross tie and at the holsters 31. ln this embodiment of the invention the holsters will each be provided With two studs 32 (Fig. 10) and the center sill sections will be connected at the holsters in all substantial respects in the same manner as they are connected at the cross ties as shown in Fig. 2, and the center late 325 (Fig. 11) also fastened in place in like manner.

My invention provides a strong and sub-` stantial underiraine which can be easily inade and pnt together. 'lhe center sill sections, the cross ties and the holsters iii'ay all 'be made of cast steel and the end sills and side sills may also be inadc oi cast steel if' desired. rlhe studs on the holsters and cross ties strengthen the connection between these parts and the center sill and add to the strength and rigidity of the umler'r'raiiie, and the studs on the cross ties strengthen the connection between the sections of the center sill, Diagonal braces Ilan'd cross braces 35 may be used wherever they are found desirable. The end sections ofthe center sill ina)` be cast integral with the yend sills or with the holsters but it is not considered necessary to g y illustrate such modifications.
